With superior ingenuity and amazingly sexy style, no vehicle is more revered than an exclusive Infiniti. Infiniti is a respected dealer of durable and powerful cars that also offer aggressive detailing and sporty looks on the track. Sporty vehicles, like your stylish Infiniti QX4, were manufactured to be used past tolerances, but afterwards serviced and maintained. Infiniti is a renowned producer recognized for engineering vehicles that offer unique styling and long lasting durability. Competing cars can't match the knockout design of the beautiful genuine Infiniti, and they're not as exquisitely constructed. For reliability, budget-friendly pricing and clean lines, choosy collectors choose cars built by Infiniti. Maximum engine power and road performance rely on first-rate parts and accessories. Positioned near the exhaust manifold, your car's Infiniti QX4 Oxygen Sensor reports oxygen levels measured in the engine's fuel system to the engine computer. A quality Infiniti QX4 Oxygen Sensor measures the oxygen level that is forced your Infiniti's engine cylinders. When your car's ratio of fuel to air is too low, reduced performance will be the consequence; at the same time, a too-rich fuel mix leads to harm to your motor and unwanted unburned fuel from the car or truck's exhaust. Your Infiniti QX4 Oxygen Sensor is a system used to regulate the oxygen level in the vehicle's exhaust. When there are any questions about our accessories, our customer service specialists can be reached via e-mail or telephone - with the usual outstanding customer service!

Very Satisfied
Reviewer: Israel

The part was ordered and it was cheaper than what we will pay for it in the local store and the exact same quality. The part arrived on schedule and it was exactly what was displayed on the website. The parts arrived in a well packaged pack and no damaged was noticed on the parts. Good job parts geek.

Somewhat Satisfied
Reviewer: BOSCH

PartsGeek had the best prices and options on the net. I searched for my left down stream OS and the average price was $25 more than what I paid for and the local stores wanted $50 more.

Their shipping cost was reasonable as well...I'm satisfied and would recommend ordering from these guys.
